Subject: [PATCH v3] dt-bindings: mfd: convert to yaml Qualcomm SPMI PMIC
Convert Qualcomm SPMI PMIC binding to yaml format.
Additional changes:
- filled many missing compatibles
Co-developed-by: Caleb Connolly <caleb@...nolly.tech>
Signed-off-by: David Heidelberg <david@...t.cz>
---
v3:
- added subnodes, there are two not converted to YAML yet, but it works
- now it prints milion directly unrelated warning to this binding
(it's related to the included subnodes bindings, can be merged,
but it'll generate more warnings and preferably anyone can takeover
from here)
- add qcom,pmx65
v2:
- changed author to myself, kept Caleb as co-author
- moved nodename to properties
- add nodenames for pm* with deprecated property
- add ^$ to pattern properties
- dropped interrupt-names property
- added reg prop. to the nodes which have register in nodename
- added compatible pmx55

- Qualcomm SPMI PMICs multi-function device bindings
-
-The Qualcomm SPMI series presently includes PM8941, PM8841 and PMA8084
-PMICs. These PMICs use a QPNP scheme through SPMI interface.
-QPNP is effectively a partitioning scheme for dividing the SPMI extended
-register space up into logical pieces, and set of fixed register
-locations/definitions within these regions, with some of these regions
-specifically used for interrupt handling.
-
-The QPNP PMICs are used with the Qualcomm Snapdragon series SoCs, and are
-interfaced to the chip via the SPMI (System Power Management Interface) bus.
-Support for multiple independent functions are implemented by splitting the
-16-bit SPMI slave address space into 256 smaller fixed-size regions, 256 bytes
-each. A function can consume one or more of these fixed-size register regions.
-
-Required properties:
-- compatible: Should contain one of:
- "qcom,pm660",
- "qcom,pm660l",
- "qcom,pm7325",
- "qcom,pm8004",
- "qcom,pm8005",
- "qcom,pm8019",
- "qcom,pm8028",
- "qcom,pm8110",
- "qcom,pm8150",
- "qcom,pm8150b",
- "qcom,pm8150c",
- "qcom,pm8150l",
- "qcom,pm8226",
- "qcom,pm8350c",
- "qcom,pm8841",
- "qcom,pm8901",
- "qcom,pm8909",
- "qcom,pm8916",
- "qcom,pm8941",
- "qcom,pm8950",
- "qcom,pm8953",
- "qcom,pm8994",
- "qcom,pm8998",
- "qcom,pma8084",
- "qcom,pmd9635",
- "qcom,pmi8950",
- "qcom,pmi8962",
- "qcom,pmi8994",
- "qcom,pmi8998",
- "qcom,pmk8002",
- "qcom,pmk8350",
- "qcom,pmr735a",
- "qcom,smb2351",
- or generalized "qcom,spmi-pmic".
-- reg: Specifies the SPMI USID slave address for this device.
- For more information see:
- Documentation/devicetree/bindings/spmi/spmi.yaml
-
-Required properties for peripheral child nodes:
-- compatible: Should contain "qcom,xxx", where "xxx" is a peripheral name.
-
-Optional properties for peripheral child nodes:
-- interrupts: Interrupts are specified as a 4-tuple. For more information
- see:
- Documentation/devicetree/bindings/spmi/qcom,spmi-pmic-arb.yaml
-- interrupt-names: Corresponding interrupt name to the interrupts property
-
-Each child node of SPMI slave id represents a function of the PMIC. In the
-example below the rtc device node represents a peripheral of pm8941
-SID = 0. The regulator device node represents a peripheral of pm8941 SID = 1.
-
-Example:
-
- spmi {
- compatible = "qcom,spmi-pmic-arb";
-
- pm8941@0 {
- compatible = "qcom,pm8941", "qcom,spmi-pmic";
- reg = <0x0 SPMI_USID>;
-
- rtc {
- compatible = "qcom,rtc";
- interrupts = <0x0 0x61 0x1 IRQ_TYPE_EDGE_RISING>;
- interrupt-names = "alarm";
- };
- };
-
- pm8941@1 {
- compatible = "qcom,pm8941", "qcom,spmi-pmic";
- reg = <0x1 SPMI_USID>;
-
- regulator {
- compatible = "qcom,regulator";
- regulator-name = "8941_boost";
- };
- };
- };
